Construction and operating principle
As the piston travels, it progressively closes metering holes and changes the oil-flow area. A return spring resets the absorber for the next impact.
Applications and selection
Automation mechanisms and precision motion stops. Match impact speed, effective mass and energy to the selected model.
Mounting and configuration
Mounting nuts and stop collars are specified separately. Flange and side-load adapter options vary across the small and larger EN ranges; use the matching accessory table for the selected model.
Force–stroke response explained
Catalogue schematic comparing force–stroke responses under different mass and speed conditions. Curves are illustrative and not to scale.
